  • Medical Device Link . Chlorine-Free Blends for Flexible Medical Tubing
    available on the market. Tubing made by one device company, for instance, employs a polybutadiene-based material that is translucent and kinks easily. Another tubing made by a different company features a three-layer construction, with the outer layer consisting of plasticized PVC and the inner layer
  • A bright idea for the operating room
    , designers wanted to reduce costs by consolidating parts via metal-to-plastic conversion. "The switch to plastic would give us more flexibility for future versions of the lamp," Nieminen says. The company chose a 30% glass-fiber-reinforced blend of polybutadiene terephthalate (PBT) and polyethylene
  • Polystyrene
    in the process are usually below 50 psi, allowing the use of relatively low-cost aluminum tooling. Unmodified polystyrene is rigid and brittle, has moderate strength, and is crystal clear. Impact strength is increased significantly by blending the polymer with rubbers such as polybutadiene. Heat
  • Oil-Resistant Rubbers
    These rubbers include grades suitable for service at temperatures to 250 C and having maximum resistance to oils and greases. Some are considered specialty materials and are quite expensive. (CR; BC, BE): Except for polybutadiene and polyisoprene, neoprene is perhaps the most rubberlike of all
  • Out of the Lab and Onto the Links

  • Medical Device Link .
    . The booklet includes the most complete line of polybutadiene polymers and coatings available. Other specialty chemicals include functional liquid and metallic monomers, oligomers, photoinitiators, and Norsolene hydrocarbon resins. Low cyclic dimer reduces scaling and promotes long run times.

    and silicone as replacements for PVC; and polymers such as ethylene vinyl acetate, polyolefins, polyesters and polybutadiene have also been investigated as potential replacements. For some manufacturers phthalates are not a concern because they do not use PVC much or their products are used
  • Medical Device Link .
    /acrylonitrile butadiene styrene (PC/ABS) blends have been engineered for a variety of thin-wall applications. Also, super-high-flow, glass-filled polybutadiene terephthalate (PBT) materials may be suited for some applications, including internal electrical components. A simple comparison
